Now you just need to configure a Lambda to take care of cache invalidation on CloudFront, based on s3:PutObject events. CloudFront also supports headers like "cache-control: public, max-age=3600, s-maxage=86400", so you can have quite aggressive caching on CloudFront where you can just invalidate it on demand anyway. Personally I just listen for any event and invalidate all objects, since that's way cheaper than issuing an invalidation request for each object, but performance wise that might not be the best option.
